Dat flow doh

Like other dohs designed for play, Mad Mattr is a molding compound that easily packs to form almost any shape you can imagine. But stretch it out and you'll find out what makes this material different. The play clay transforms to a light, airy handful of fluff that's like massaging a cloud. Once you've stretched it to its breaking point, smush it back together and start all over again.

Get your hands on this strange stretchy stuff.

Shape and stretch

Mad Mattr is infinitely moldable. Compact and compress it, meld pieces together, and easily scrape bits away to make your imagination come to life in bright colors. The very same stuff also stretches in soft, air-filled ropes that feel like pillars of pillows.

Mad Mattr is whatever you want it to be.

Minimal mess

Messing with Mad Mattr isn't messy at all. That's because the nature of the clay makes it stick to itself, so you can use a clump of the clay to pick up more of it. Think of it as a kind of a whack-a-mole fun game!

Everybody do your share.

Satisfying to slice

Cutting through Mad Mattr is one of those oddly enjoyable experiences that satisfies all of your senses and gets your brain tingling. You'll have to pick up your own batch to try it yourself, but crank up the volume and watch this video while you wait for your order to arrive.

But it feels so right.

Terrific toy

Parents can feel good about Mad Mattr because it never dries out and is non-toxic. Kids can feel good about Mad Mattr because it feels awesome to play with.

The super-powered modeling compound is currently available in blue, green, and pink.

Feel the fluff.

Build bricks

Take your Mad Mattr molding to the next level with Lego brick-inspired building blocks. The optional Ultimate Brick Maker Set enables you to make perfect-specification building blocks that actually lock together.

Simply add a wad of Mattr, give the press a squeeze, and remove your newly formed brick complete with pips on top. Stack them together, and they're unlikely to topple. But since they're made of Mad Mattr, you can still enjoy smashing your structure before packing the bricks again.

Please note: The Brick Maker Set includes the plastic pieces shown below as well as 2 ounces of Blue Mad Mattr.

No matter how hard you huff and puff, these bricks aren't blowin' down.

Frequently Asked Questions

Question: What happens if I combine different colors?

Answer: When you blend two different colors of Mad Mattr, the color will change to a grade between the two colors. For example, combining blue and green Mad Mattr creates teal Mad Mattr that works and feels just like its original parent colors. Once combined, Mad Mattr will not easily separate back to the original colors.

Question: Can you light Mad Mattr on fire?

Answer: That's somewhat of a dangerous question, but we certainly tackled it in our Burning Questions video below.

Question: What happens if I combine it with other modeling compounds or play sands?

Answer: Mad Mattr will lose some of its special properties if you mix it with other stuff, so we don't recommend it.
